Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

Equivalent Wattages Between Different Light Bulbs

As long as the technology developed, a LED light bulb can only use 8 watt power but light up similar brightness when a incandescent light bulb uses 60 watt power. There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

25° Focused Beam

MR16 halogen lamp producing 490 lumens of 3050K warm white light.

ConstantColor Precise

Reflector coating with UV Control and a glass-covered face.

⚠️ Important: This is a 12V low voltage bulb and requires a compatible 12V transformer or power supply. It will not work with standard 240V mains voltage.

This GE Precise MR16 halogen lamp produces a focused 25° beam with 490 lumens of 3050K warm white light. It features a ConstantColor reflector coating, UV Control and a glass-covered face.

The lamp draws 50W and uses a GU5.3 two-pin base. Match the fitting and 12V supply to the actual 50W load, and follow the fitting manufacturer's ventilation and heat-clearance requirements. For dimming, use a compatible halogen dimmer and dimmable 12V supply within their minimum and maximum load ratings.

Delivered quickly, very very expensive, but also very very hard to find narrow angle halogens (not LED’s).
